VSTS Connection error TF 14045

Hy to all , 

I have a collection of projects in azure devops and I try to give permission to a specific user to access certain projects. I have tried to give him the permissions with a basic role and both in the Project Contribuitors  group or in administrator groups but the VSTS  give same erroir always "TF 14045 error always occurs: The identity [user@email.com] is not recognized identity."

This does not happen with other users, only with one.

I tested with Visual Studio 2017 and  Eclipse, i clean cache of team foundation , visual studio  and the error is the same in several PCs

Log for eclipse
